TIP
Air filter and V-belt filter
This model’s air filter is equipped wi th a disposable oil-coated paper elemen t, which must not be cleaned with com-
pressed air to avoid damaging it.
The air filter element needs to be replaced and V-belt filter needs to be serviced more frequently when riding in un- usually wet or dusty areas.
Hydraulic brake service
After disassembling the brake master cylinder and caliper , always change the fluid. Regularly check the brake fluid
level and fill the reservoir as required.
Every two years replace the internal components of the brake master cylinder and caliper, and change the brake fluid. Replace the brake hose every four years and if cracked or damaged.

Checking the spark plugThe spark plug is an important engine
component, which is easy to check.
Since heat and deposits will cause any
spark plug to slowly erode, the spark
plug should be removed and checked
in accordance with the periodic mainte-
nance and lubrication chart. In addition,
the condition of the spark plug can re-
veal the condition of the engine.
To remove the spark plug 1. Place the vehicle on the center- stand.
2. Remove panel C. (See page 6-8.)
3. Remove the spark plug cap.
4. Remove the spark plug as shown, with the spark plug wrench includ-
ed in the owner’s tool kit. To check the spark plug
1. Check that the porcelain insulator around the center electrode of the
spark plug is a medium-to-light tan
(the ideal color when the vehicle is
ridden normally).
TIPIf the spark plug shows a distinctly dif-
ferent color, the engine could be oper-
ating improperly. Do not attempt to
diagnose such problems yourself. In-
stead, have a Yamaha dealer checkthe vehicle.
2. Check the spark plug for electrode erosion and excessive carbon or
other deposits, and replace it if

12 necessary.
3. Measure the spark plug gap with a wire thickness gauge and, if nec-
essary, adjust the gap to specifica-
tion.
To install the spark plug 1. Clean the surface of the spark plug gasket and its mating surface, and
then wipe off any grime from the
spark plug threads.
2. Install the spark plug with the spark plug wrench, and then tight-
en it to the specified torque.
TIPIf a torque wrench is not available when
installing a spark plug, a good estimate
of the correct torque is 1/4–1/2 turn past finger tight. However, the spark
plug should be tightened to the speci-
fied torque as soon as possible.
3. Install the spark plug cap.
4. Install the panel.
EAUT3703
Engine oil and oil strainerThe engine oil level should be checked
before each ride. In addition, the oil
must be changed and the oil strainer
cleaned at the intervals specified in the
periodic maintenance and lubrication
chart.
To check the engine oil level
1. Place the scooter on the center- stand. A slight tilt to the side can
result in a false reading.
2. Start the engine, warm it up for several minutes, and then turn it
off.
3. Wait a few minutes until the oil set- tles, remove the oil filler cap, wipe
the dipstick clean, insert it back
into the oil filler hole (without
screwing it in), and then remove it
again to check the oil level.TIPThe engine oil should be between theminimum and maximum level marks.
Specified spark plug:NGK / CPR9EA-9
Spark plug gap: 0.8–0.9 mm (0.031–0.035 in)
Tightening torque: Spark plug: 13 Nm (1.3 m·kgf, 9.4 ft·lbf)

4. If the engine oil is below the mini-
mum level mark, add sufficient oil
of the recommended type to raise
it to the correct level.
5. Insert the dipstick into the oil filler hole, and then tighten the oil filler
cap.
To change the engine oil and clean
the oil strainer 1. Start the engine, warm it up for several minutes, and then turn it
off.
2. Place an oil pan under the engine to collect the used oil. 3. Remove the engine oil filler cap
and the engine oil drain bolts A
and B to drain the oil from the
crankcase. NOTICE: When re-
moving the engine oil drain bolt
B, the O-ring, compression
spring, and oil strainer will fall
out. Take care not to lose these
parts.

4. Clean the oil strainer with solvent, and then check it for damage and
replace it if necessary.
